NAME
condor_config_val - HTCondor Manual
Query or set a given HTCondor configuration variable
SYNOPSIS
condor_config_val <help option>
condor_config_val [<location options> ] <edit option>
condor_config_val [<location options> ] [<view options> ] vars
condor_config_val use category [:template_name ] [-expand ]
DESCRIPTION
condor_config_val can be used to quickly see what the current HTCondor configuration is on
any given machine. Given a space separated set of configuration variables with the vars
argument, condor_config_val will report what each of these variables is currently set to.
If a given variable is not defined, condor_config_val will halt on that variable, and
report that it is not defined. By default, condor_config_val looks in the local machine's
configuration files in order to evaluate the variables. Variables and values may instead
be queried from a daemon specified using a location option.
Raw output of condor_config_val displays the string used to define the configuration
variable. This is what is on the right hand side of the equals sign (=) in a configuration
file for a variable. The default output is an expanded one. Expanded output recursively
replaces any macros within the raw definition of a variable with the macro's raw
definition.
Each daemon remembers settings made by a successful invocation of condor_config_val. The
configuration file is not modified.
condor_config_val can be used to persistently set or unset configuration variables for a
specific daemon on a given machine using a -set or -unset edit option. Persistent settings
remain when the daemon is restarted. Configuration variables for a specific daemon on a
given machine may be set or unset for the time period that the daemon continues to run
using a -rset or -runset edit option. These runtime settings will override persistent
settings until the daemon is restarted. Any changes made will not take effect until
condor_reconfig is invoked.
In general, modifying a host's configuration with condor_config_val requires the CONFIG
access level, which is disabled on all hosts by default. Administrators have more
fine-grained control over which access levels can modify which settings. See the Security
section for more details on security settings. Further, security considerations require
proper settings of configuration variables SETTABLE_ATTRS_<PERMISSION-LEVEL>,
ENABLE_PERSISTENT_CONFIG, and ALLOW in order to use condor_config_val to change any
configuration variable.
It is generally wise to test a new configuration on a single machine to ensure that no
syntax or other errors in the configuration have been made before the reconfiguration of
many machines. Having bad syntax or invalid configuration settings is a fatal error for
HTCondor daemons, and they will exit. It is far better to discover such a problem on a
single machine than to cause all the HTCondor daemons in the pool to exit.
condor_config_val can help with this type of testing.
OPTIONS
-help (help option) Print usage information and exit.
-version
(help option) Print the HTCondor version information and exit.
-set "var = value"
(edit option) Sets one or more persistent configuration file variables. The new
value remains if the daemon is restarted. One or more variables can be set; the
syntax requires double quote marks to identify the pairing of variable name to
value, and to permit spaces.
-unset var
(edit option) Each of the persistent configuration variables listed reverts to
its previous value.
-rset "var = value"
(edit option) Sets one or more configuration file variables. The new value
remains as long as the daemon continues running. One or more variables can be
set; the syntax requires double quote marks to identify the pairing of variable
name to value, and to permit spaces.
-runset var
(edit option) Each of the configuration variables listed reverts to its previous
value as long as the daemon continues running.
-summary[:detected]
(view option) For all configuration variables that differ from default value,
print out the name and value. The values are grouped by the file that last set
the variable, and in the order that they were set in that file. If the detected
option is added, then variables such as $(OPSYSANDVER) that are detected at
runtime are included in the ouput.
-dump (view option) For all configuration variables that match vars, display the
variables and their values. If no vars are listed, then display all
configuration variables and their values. The values will be raw unless -expand,
-default, or -evaluate are used.
-default
(view option) Default values are displayed.
-expand
(view option) Expanded values are displayed. This is the default unless -dump is
used.
-raw (view option) Raw values are displayed.
-verbose
(view option) Display configuration file name and line number where the variable
is set, along with the raw, expanded, and default values of the variable.
-debug[:<opts>]
(view option) Send output to stderr, overriding a set value of TOOL_DEBUG.
-evaluate
(view option) Applied only when a location option specifies a daemon. The value
of the requested parameter will be evaluated with respect to the ClassAd of that
daemon.
-used (view option) Applied only when a location option specifies a daemon. Modifies
which variables are displayed to only those used by the specified daemon.
-unused
(view option) Applied only when a location option specifies a daemon. Modifies
which variables are displayed to only those not used by the specified daemon.
-config
(view option) Applied only when the configuration is read from files (the
default), and not when applied to a specific daemon. Display the current
configuration file that set the variable.
-writeconfig[:upgrade] filename
(view option) For the configuration read from files (the default), write to file
filename all configuration variables. Values that are the same as internal,
compile-time defaults will be preceded by the comment character. If the :upgrade
o ption is specified, then values that are the same as the internal,
compile-time defaults are omitted. Variables are in the same order as the they
were read from the original configuration files.
-macro[:path]
(view option) Macro expand the text in vars as the configuration language would.
You can use expansion functions such as $F(<var>). If the :path o ption is
specified, treat the result as a path and return the canonical form.
-mixedcase
(view option) Applied only when the configuration is read from files (the
default), and not when applied to a specific daemon. Print variable names with
the same letter case used in the variable's definition.
-local-name <name>
(view option) Applied only when the configuration is read from files (the
default), and not when applied to a specific daemon. Inspect the values of
attributes that use local names, which is useful to distinguish which daemon
when there is more than one of the particular daemon running.
-subsystem <daemon>
(view option) Applied only when the configuration is read from files (the
default), and not when applied to a specific daemon. Specifies the subsystem or
daemon name to query, with a default value of the TOOL subsystem.
-address <ip:port>
(location option) Connect to the given IP address and port number.
-pool centralmanagerhostname[:portnumber]
(location option) Use the given central manager and an optional port number to
find daemons.
-name <machine_name>
(location option) Query the specified machine's condor_master daemon for its
configuration. Does not function together with any of the options: -dump,
-config, or -verbose.
-master | -schedd | -startd | -collector | -negotiator
(location option) The specific daemon to query.
use category [:set name ] [-expand ]
Display information about configuration templates (see
admin-manual/introduction-to-configuration:configuration templates). Specifying
only a category will list the template_names available for that category.
Specifying a category and a template_name will display the definition of that
configuration template. Adding the -expand option will display the expanded
definition (with macro substitutions). (-expand has no effect if a template_name
is not specified.) Note that there is no dash before use and that spaces are not
allowed next to the colon character separating category and template_name.
EXIT STATUS
condor_config_val will exit with a status value of 0 (zero) upon success, and it will exit
with the value 1 (one) upon failure.
EXAMPLES
Here is a set of examples to show a sequence of operations using condor_config_val. To
request the condor_schedd daemon on host perdita to display the value of the
MAX_JOBS_RUNNING configuration variable:
$ condor_config_val -name perdita -schedd MAX_JOBS_RUNNING
500
To request the condor_schedd daemon on host perdita to set the value of the
MAX_JOBS_RUNNING configuration variable to the value 10.
$ condor_config_val -name perdita -schedd -set "MAX_JOBS_RUNNING = 10"
Successfully set configuration "MAX_JOBS_RUNNING = 10" on
schedd perdita.cs.wisc.edu <128.105.73.32:52067>.
A command that will implement the change just set in the previous example.
$ condor_reconfig -schedd perdita
Sent "Reconfig" command to schedd perdita.cs.wisc.edu
A re-check of the configuration variable reflects the change implemented:
$ condor_config_val -name perdita -schedd MAX_JOBS_RUNNING
10
To set the configuration variable MAX_JOBS_RUNNING back to what it was before the command
to set it to 10:
$ condor_config_val -name perdita -schedd -unset MAX_JOBS_RUNNING
Successfully unset configuration "MAX_JOBS_RUNNING" on
schedd perdita.cs.wisc.edu <128.105.73.32:52067>.
A command that will implement the change just set in the previous example.
$ condor_reconfig -schedd perdita
Sent "Reconfig" command to schedd perdita.cs.wisc.edu
A re-check of the configuration variable reflects that variable has gone back to is value
before initial set of the variable:
$ condor_config_val -name perdita -schedd MAX_JOBS_RUNNING
500
Getting a list of template_names for the role configuration template category:
$ condor_config_val use role
use ROLE accepts
